BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circuit breaker having a box including a triggering / resetting mechanism that is easy to act on a separate contact for opening and closing at least one current path. On the box of this circuit breaker, the through-control window (opening part) for an on control button and an off control button which an operator can use is formed.

Such circuit breakers are clearly described in French Patent No. 2,448,216. These control buttons are push buttons mounted on the box, and are slidable alternately between two operating positions and have a front pressing surface to which an operator's finger touches. When the operator wants to close the contact, when the operator presses the on pushbutton, the on pushbutton remains pressed while the off pushbutton automatically pops out to the outward position with respect to the box. Conversely, if the operator wants to open the contact, when the operator presses the off push button, the off push button is kept pressed while the on push button automatically returns to the outer position. In this way, the position of the push button is alternately positioned, the operator can clearly know the state of the circuit breaker.

Although such a manual control device is satisfactory, on the one hand it is desirable to improve on its ergonomics, while on the other hand it is desired to emphasize the indication of its on or off state noticeably.

Further, French Patent No. 1,558,448 discloses a command transmission configuration to an electric switch by a pivot-type button having a transparent window, and the display showing two operation positions can be seen by this transparent window. In particular, command transmission to a circuit breaker is known by a pivot type control button called a tumbler to which a triggering display means is connected. However, these known pivot type control buttons could not fully satisfy the desired work safety and clear display.

SUMMARY OF THE INVENTION The main object of the present invention is to provide ergonomic manual control for separating the on / off control function while displaying a good on-state, preferably on / off, state of the circuit breaker. To provide a circuit breaker that can be compromised.

Another object is to facilitate locking of the manual control device in its off position.

According to the present invention, the on / off button of the circuit breaker is pivotally mounted to the circuit breaker box, and the pressing surface of each button is unique, and the first end and the displacement amount are small in the amount of displacement in which the pivot gudgeon is located in the vicinity. The range is defined by this large second end, and the mechanism is coupled to the pivot arm of the button at least in the on position to generate a height difference in the frontal projection of the second end relative to the on-button of the off-button. It is characterized by being.

The control buttons are preferably arranged side by side so as to pivot about a common axis located approximately at the side level of the box perpendicular to the front side thereof, so that not only the difference in the front height of those second ends but also the distinct protruding state can be obtained. Therefore, the display of the state can be made fully visible. This display is preferably provided in a box near the first end of the pressing face, in particular in the action of the button, and on display means alternately exposed and concealed by opposing transparent windows provided on the first end and / or the pressing face. Is confirmed by

On the second end of the pressing face and on the opposite side thereof, a stop face applied to the front of the box on the one hand and an arm for operating the mechanism on the other hand are provided, and this arm is provided for passing the lock, An opening on the horizontal axis is formed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited thereto.

The electrical device shown in the figure is a circuit breaker called a motor circuit breaker, which is easy to act on a movable contact detachable from a fixed contact to open and close several current paths connected between each pair of terminals 11 and 12. It consists of the box 10 containing this attached triggering reset mechanism.

The motor circuit breaker has two windows (openings) 15 and 16 formed on the front wall 17 of the protrusion 18 protruding into the nose of the box 10 so as to interact with the mechanism. It is provided with two buttons 13 and 14 which move side by side and are mounted side by side in a rotatable manner about the cavity axis X. As a modification, the buttons may be mounted by other methods besides mounting the buttons side by side in parallel as described above. When spontaneous or automatic commands are applied, the buttons alternately take inward and outward positions relative to the front wall 17, opposite to each other. In addition, the buttons 13 and 14 are coupled to the mechanism via the control unit 19 (see Figs. 2 and 3) and cooperate with the mechanism and are perpendicular to the plane including the axis X (Y). It turns around.

Hereinafter, the pivot type on button 14 will be described with reference to FIGS. 2 to 4. The pressing surface 20 for the operator to press with a finger is flat, but may be slightly concave or convex, which pressing surface has two ends 20a and 20b and is unique, i.e. By pressing, the button works in only one direction.

The first end 20a of the pressing surface 20 has a small amount of displacement determined by the vicinity of the axis X of the ground 21 which pivots the button, and the first end 20a has a role thereafter. This inclined edge 22 is provided.

The button 14 is slidable on the ground 21 near the end 20a of the pressing surface 20 and on the opposite side of the pressing surface, ie inside the box, on the one hand by one side 23a and on the other hand. Has two curved pivot arms 23 which are slidable on the stationary bearing member 24 by its opposing surfaces 23b. The bearing member 24 extends toward the front wall 17 of the box by display means 25 which can appear on the opposite side of the window 26 of the button when the button is in its inner operating position. The window 26 is made of a transparent material.

The button has a control arm 27 which cooperates with the control unit 19 of the mechanism near the end 20b of the pressing surface and on the opposite side of the pressing surface. To this end, the control arm 27 is coupled to the slug 29 of the control unit 19 to cooperate with each other to operate the control unit 19 or to have a shape that can be operated by the control unit 19. The frame 28 is assembled. The stopper 30 installed near the free end of the control arm 27 serves to elastically introduce the button 14 into the window 16 and abuts the corner of the window 16 or is installed in the box. Contact another stopper to prevent the button from slipping out. Finally, the control arm 27 has an opening 31 through which the lock for holding the button in the outward position passes.

The surface of the ground 21 has a display area 32 at an end located toward the front face 17 of the box. The display area 32 has, for example, an ON display for the button 14 and an OFF display for the button 13 (see FIGS. 1, 5, 8, and 9), The first end portion of the pressing surface 20, that is, the end portion 20a having a small displacement amount, is exposed and concealed alternately. In the operation position of each pair of two buttons, one of the display areas of the buttons is exposed and the other is concealed. That is, in FIG. 2, it can be seen that the end portion 20a of the pressing surface 20 covers the display area 32, wherein the inclined edge 22 is a box perpendicular to the front surface 17. While in Fig. 3, with the aid of the shape of the inclined edge 22, the end portion 20a reveals the display area 32, while being aligned with the portion adjacent to the horizontal side 18a of the projection 18 of Figs. You can see that.

The button travels to the inside of the button with respect to the inner edge 35 or the side edge 36 of the window 16 of the front face 17 near the edge of the pressing surface 20 and the opposite side of the pressing surface. In order to limit this, the stop surfaces 33 and 34 are applied.

5, 8 and 9, the reference numerals for the buttons 13 are denoted by the symbol (') as necessary to distinguish the member of the button 13 from the member of the button 14 corresponding thereto. Bookkeeping.

As can be seen from FIG. 5, each ground 21 is allowed to stop in two rest portions 37, 38 cooperating with each pivot arm 23, and each display means 25, 25 '. For example,? For the off button 13 and? For the on button 14 are applied to the horizontal arms 39 and 39 'of the ring member for determining the sliding surface of at least one arm 23. Supported by

The window 16 for the on button 14 is slightly longer than the window 15 for the off button 13 because the corresponding control arm 27 with the opening 31 is longer. In addition to the lower edge 41 of the window, an intermediate horizontal edge 42 is added to guide each cylindrical surface 43, 44 of the button.

The pivoted off button 13 is shown in FIGS. 6 and 7 and is substantially similar to the button 14, so further description thereof is omitted, except that the control arm 27 is provided with an opening 31. Since it does not need to be provided, it is shorter than for the button 14. In addition, a lower groove-shaped stripe 45 or other non-slip means can be provided below the pressing surface 20 of the two buttons.

Each pivot type button is mounted to the circuit breaker box in the following manner. After the free end of the pivot arm 23 is inserted between the ground 21 and the bearing member 24, the stopper 30 passes through a hard point associated therewith, and the control arm 27 is a slug of the control unit 19. Is joined by its frame 28 on 29. In order to close the contacts of the circuit breaker, when the operator presses the on button 14, the mechanism causes the off button 13 to pop out. Thereafter, only the ON display area 32 and the? Display means 25 of the button 14 are visible (FIG. 9). On the other hand, when the operator presses the off button 13 to open the contact, the on button pops up to the inside position, and only the OFF display area 32 'and the? Display means 25' of the button 13 are visible. (Figure 8). As can be seen from FIGS. 8 and 9, the end 20b of the on button 14 is located in the on and off states of the circuit breaker at a different level than the end 20b 'of the off button 13. Thus, whether the off button is operated in the current holding mode or the pulse mode, it is moved by both the height difference h of the front projection of the lower edge of the button and the projection distinct from the front surface 17.

In the modifications of Figs. 10 and 11, the opening 31 for lock passing is formed in the pull 5, more precisely in the wide part 51 of the pull, and the grass is visible to the eyes. It is housed in the on-button 14 to take a non-obvious position (FIG. 10) and an outer locking position (FIG. 11). The wide part 51 of the pool is located near the end 20b where the amount of displacement of the button is large. In addition, the pool has a rear portion 52 provided with an opening 53 whose upper edge cooperates with the stopper 54 of the box and restrains the pool to the outer locking position. In addition, the pull cooperates with its frame 55 in the button 14 by means of a suitable guide and stop surface, which is held in an inconspicuous position by means of a stop or retaining means, and against the front face 17 of the box. Stop at position When the lock 56 is provided in the opening part 31, contact with the arm 27 prevents the pool from returning to an inconspicuous position.

The present invention can be applied to any circuit breaker or directional relay as long as it can compromise safety of manual operation and good state display.
